Two one-dimensional Luttinger liquid systems coupled by Hund's coupling are
studied by the renormalization group and the non-abelian bosonization methods.
It is found that the Hund's coupling is always relevant irrespective of the
repulsive interaction between electrons within each chain.
The properties of the resulting strong coupling fixed point are discussed.
